Researchers build Moon garden

first_imgMurat Kacira at the Controlled Environment Agriculture Center. Image credit: Norma Jean Gargasz/UANews. Developed by Phil Sadler of the Sadler Machine Co. and Gene Giacomelli and other researchers at the University of Arizona, the 18-foot-long greenhouse would be buried underneath the Moon’s surface to avoid deadly cosmic rays and solar flares. Plants can grow without soil in the greenhouse thanks to hydroponic technology, mineral nutrient solutions, and long envelopes that hold the seeds in place as they start growing.The greenhouse is designed so that the plants can get carbon dioxide from the astronauts’ exhaled breaths. Furthermore, even the water for the plants can be extracted from human urine. The astronauts wouldn’t need to go underground to deliver these ingredients to the plants; instead, the carbon dioxide and water would be supplied into the underground greenhouse from a surface lunar base through pressurized tanks. Similarly, sunlight could be supplied to the plants through fiber optic cables. The researchers designed the greenhouse to operate remotely or even autonomously, so that food could be ready when astronauts arrive. The entire system can be collapsed into a four-foot-wide disk, sent to the Moon, and deployed in 10 minutes. With the option of being monitored from Earth by sensors and cameras, it will then take about 30 days for the vegetables to grow.”You can think of this as a robotic mechanism that is providing food, oxygen and fresh drinking water,” Giacomelli said in a press release.Overall, the lunar greenhouse contains approximately 220 pounds of wet plant material that can provide 53 quarts of potable water and 0.75 pounds of oxygen during a 24-hour period, while consuming about 100 kilowatts of electricity and a pound of carbon dioxide. Many of the garden’s features come from the South Pole Growth Chamber here on Earth, which was previously designed by the Sadler Machine Co. The growth chamber has to overcome some of the same challenges for certain months of the year when the circulating ocean currents cut the pole off from the rest of the world. The researchers are also looking at using similar technology for use in urban gardens in heavily populated areas, where fertile soil is scarce.”There’s great interest in providing locally grown, fresh food in cities, for growing food right where masses of people are living,” Giacomelli said. “It’s the idea of growing high-quality fresh food that only has to be transported very short distances. There also would be a sense of agriculture returning to the everyday lives of urban dwellers.” The Moon is not the most hospitable place for growing fruits and vegetables. The lack of atmosphere and natural water, extreme temperatures, and exposure to cosmic rays present some serious challenges for future inhabitants who want to pursue sustainable living on the Moon. With these challenges in mind, scientists have built a lunar greenhouse that is designed to grow plants such as potatoes, peanuts, tomatoes, and peppers under the Moon’s extreme conditions.

They think it might cost a lot of money and are surprised when you tell them it might be $3,000.”The student team helping Perry have a range of capabilities that have supported the project, including specialties in mechanical design, electrical design, programming, computer numerical-control machining and finite-elements analysis modeling.As lithium-battery technology improves, Perry said, the battery size can be reduced in production models. As a former IBM engineer he is no stranger to the challenges in bringing something out of a research lab and into a showroom, Perry is talking with several potential investors. He wants to use the funding to build and demonstrate a manufacturing version of this plug-in hybrid technology. This document is subject to copyright.

(Phys.org) — When news broke in 2009 that a former IBM engineer had devised a kit that turns any car into a plug-in hybrid for between $3,000 and $5,000, those interested in going-green technologies took notice and hoped it was more than just a concept. This month, Dr. Charles Perry and his team at Middle Tennessee State University, where he is now a professor, have something to show for the work that has been under way since 2008. Earlier this week, a school news release announced that Perry and team saw gas mileage increase anywhere from 50 to 100 percent on a 1994 Honda station wagon retrofitted with their laboratory prototype plug-in hybrid capability. This is a wheel-hub motor, plug in hybrid kit. © 2012 Phys.org Citation: Wheel hub motor concept drives hybrid progress at MTSU (2012, July 24) retrieved 18 August 2019 from https://phys.org/news/2012-07-wheel-hub-motor-concept-hybrid.html He and the team have reached the proof of concept stage to prove feasibility, he said, and with enough funding they can deliver proof of product. Investors, he noted, will want to see proven field-tested performance and reliability.Perry said a manufacturing partner has stepped forward and will accompany him to anticipated upcoming presentations.This would certainly not be the first or last attempt to work up a suitable retrofit kit as interest grows in hybrids. In 2008, the UK-based Motor Industry Research Association, an automotive design, development and certification consultancy, unveiled a plug-in hybrid retrofit system. The kit, they said at the time, had the potential to reduce fuel consumption and tailpipe emissions by 39 percent, and they applied it in a demo vehicle with removable lithium-ion phosphate battery pack. They built the demo with funding from the Energy Saving Trust’s Low Carbon R&D program. Explore furthercenter_img The key element in this gas-saving kit are electric motors in each rear wheel and a large lithium-ion battery, which is also mounted in the rear of the vehicle. The very point of the exercise, said Perry, now a professor in the engineering technology department of the school, has been to demonstrate the feasibility of adding an electrical motor to the rear wheel of the car without changing brakes, bearings, suspension —“anything mechanical.” Jay Perry views the rotor he has removed from the stator, which is attached to the axle bearings. In the entire process, nothing alters the car’€™s bearings, brakes or suspension.

More information: Men’s status and reproductive success in 33 nonindustrial societies: Effects of subsistence, marriage system, and reproductive strategy , PNAS, www.pnas.org/cgi/doi/10.1073/pnas.1606800113 (Phys.org)—A pair of researchers, one with the University of Richmond in Virginia, the other Emory University in Georgia, has found that the reproductive success of the modern nonindustrialized man correlates with his social status across a wide variety of society types. In their paper published in Proceedings of the National Academy of Sciences, Christopher von Rueden and Adrian Jaeggi describe the research they undertook in seeking to learn more about the role that status plays in measuring reproductive success in modern non-industrialized societies and the results they found.

But because of technological advancements, life has changed for both men and women, which means the rules for measuring reproductive success might have changed as well. It is no secret that in most modern industrialized societies, for example, men at the top of the economic ladder, unlike in previous generations, actually produce fewer offspring than do men at the middle or bottom. But the researchers wondered what is going on in unindustrialized modern societies.In this new effort, they set out to test the ‘egalitarianism hypothesis,’ which suggests that status plays a less significant role in reproductive success in societies that are still based on foraging to get their food than on those that are non-foragers (those who either grow their own food or get it another way.) To learn more, they looked at 46 prior research efforts involving 33 nonindustrial societies. They then conducted an analysis of the data looking for correlations between such factors as physical build, wealth, hunting ability and influence, with other factors such as number of sexual partners, fertility and numbers and health of offspring.The researchers report that they found that correlations that existed between the status of males in such societies and their reproductive success was not much affected by the way in which they made a living—instead, they were much more influenced by the marriage system in place. Societies that were polygamous, they found, had more associations between offspring mortality and status. In polygamous societies, there were more associations between what was deemed a quality wife and status. These findings suggest, the researchers note, that traits that helped a man acquire status were not necessarily tied to the means by which food was obtained, but by strategies that correlated with enhanced fertility, and to a lesser extent, the well-being of the offspring that were produced.

She also said mismanagement is going on. The cess imposed by Central government has been increased and no attempts are being made to bring stability in the fuel prices, Banerjee alleged. “In January, 2016 the petrol price was Rs 65.12 a litre and in September 2018 the price has risen to Rs 81.5 per litre. So the petrol price has gone up by Rs 16.48 per litre. Diesel price was Rs 48.80 a litre in 2016 ,now it has risen to Rs 73.26 per litre, which is a hike of Rs 24.46,” Banerjee said.last_img read more

What India wastes could feed Egypt

first_imgIndians waste as much food as is sufficient to meet an year’s requirement of a country like Egypt. In a survey, it was stated that in India appx. 67 lakh ton of food is getting wasted every year which is worth Rs 92000 crore. The wastage of food in India is as much as what United Kingdom consumes.Food wastage is an alarming issue in India. The wastage at weddings, social and family functions, hotels, households’ are sufficient evidence to prove it. Also Read – Add new books to your shelfBefore wasting the food just think about the following facts:How much water was used to produce the food; How much oil/ electricity was used to produce food;Acres of land are deforested to grow food;Food waste thrown to landfills, resulting in emission of greenhouse gases which causes pollution and change in climate having devastating impact on the environment;Wastage of food will result in shortage of food and dent the economy in the form of inflation; Also Read – Over 2 hours screen time daily will make your kids impulsiveIt is obvious that we are not wasting the food but national resources.Food waste from production in plants to plate can be classified as preconsumer (uneaten food) and post-consumer (thrown away food). The wastage of food resulting from the stage of production to retailing can be termed as pre-consumer food wastage. The post –consumer food waste reflects the food thrown away by consumer from plate after procuring from the retailer.For reducing food wastage in pre- consumer category infrastructure improvement (transportation, storage and distribution) for handling the food will help. In case of avoiding food wastage in post-consumer category the change is required in our cultural habits and social behavior. In this category, here are some easy ways to do your bit:In case of invitation to attend wedding/ formal/ social party, confirm your presence/absence as it will help the host to avoid over ordering. This small change in habit will help in reduction of food wastage immensely;For dinning out on buffet, take small quantity/portions first; Procure the food smartly based on weekly consumption to the extent possible. If you buy more than what you consume then the difference will naturally result in wastage;Make sure you cook the food keeping in mind a realistic requirement. You can always complete your meal with few fruits than keeping extra food in refrigerator. It is a better and healthier practice;Use FIFO (First in First Out) as a rule especially for green vegetables and fruits. Consume what you bought first;Reuse the left over if possible, for instance, stale rice makes good fried rice;Educate your children of the importance of food;In a nutshell, food should reach not garbage bins and landfills but find place in human stomach. It will bring smiles on hungry faces.last_img read more
